numbers in @Diag names

[Joe Beach]

Hello,

I use @Diag to make figures, and it is often convenient to name objects 
in the diagram with numbers, such as:

ITEM1::@Box translate {NW to 0,1} {something}
ITEM2::@Box translate {W to address@hidden {something 2}
ITEM3::@Box translate {W to address@hidden {something 3}

I sometimes run into problems with numbers in the names, in which lout 
gives an error and won't generate the diagram. If I change the names to 
something like ITEMONE, ITEMTWO, ITEMTHREE, then things work okay. Have 
other people observed this sort of behavior? I'd like to use the numbers 
because it lets me use while loops and counters in a script to place an 
array of objects on a page.
